WebThe logarithmic quantization is mainly used with linear systems with infinite quantization levels, while the zoom strategy is a beneficial control policy when uniform quantization is applied. It has two steps: “zoom-in” and “zoom-out” [17]. WebThe u-law companding used in commercial telephony in North America is given by log(1+ ula}) log(1+ u) where u z 100, x is the input signal value and y is the output signal value. Consider that the input is in the range of 0 < x < 5. (a) Draw the sample spaces that could be used to represent events involving the input and the output signals.

WebTranscribed image text: Question 40 2 Points In Europe, the ITU-T has established companding to be used to approximate true logarithmic companding. A) Digital … WebLet's assume 8 bits are used, so the number of quantization levels is 2^8 = 256. Thus, delta = 1.2/256 = 0.0046875 volts. To minimize the quantization error, we want to maximize the input signal range. The pre-amplifier should amplify the signal by a factor of 1/delta to maximize the input signal range. So, a1 = 1/delta = 213.333, and a2 = -1.2.
